The following statement is incorrect. Change two words to make it correct.

Capillary action happens when water moves up a vessel against gravity. It is a result of density and solubility working together.

NEED HELP PLZ

Answers

Answer:

Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture to right) is limited by surface tension and, of course, gravity.

Explanation:

:}

When the cohesive forces between the liquid molecules are greater than the adhesion to the walls, capillary action results. Surface tension and, of course, gravity set a limit on how high capillary action may raise water in a uniform circular tube (see image to the right).

What is Capillary action in plants?

Water is transported to the remainder of the plant by capillary action up the stems and roots. Through the plant, water is transported through capillary action.

Water (the liquid) molecules are drawn to the molecules of the stem's interior (the solid).

The purpose of this attraction is to help lift the water out of the ground and distribute it throughout the plant.

When the forces holding a liquid together—cohesion and surface tension—and the forces drawing that liquid to another surface—adhesion—are stronger than the force of gravity, capillary action takes place.

Therefore, through cohesive forces and surface tension, water moves up a vessel against gravity.

What is the function of RBCs?

Erythrocytes also referred to as red blood cells carry oxygen to your body's tissues. As oxygen is converted to energy, carbon dioxide is released by your tissues. Additionally, your red blood cells carry carbon dioxide to your lungs so you may exhale it.

The process of getting oxygen from your lungs to your body's tissues is carried out by red blood cells. Your tissues use oxygen to make energy and carbon dioxide to expel waste. The carbon dioxide waste is transported to your lungs by your red blood cells, where it is exhaled.

It takes roughly seven days for red blood cells to properly mature and are then released into the bloodstream from the soft bone tissue (bone marrow) of your body. A protein that enables red blood cells to transport oxygen from your lungs and transfer it to other tissues in your body gives them their vivid red color is called hemoglobin.

Therefore, all of these cells have a high surface area-to-volume ratio.

What does the term temperature control refer to

Answers

Answer:

the term temperature control refers to Thermostats .....

A device called a temperature controller is used to maintain a target temperature at a given level. The typical thermostat seen in homes is the most basic type of temperature controller.

What are the biological temperature control factors?

The hypothalamus, a region of the brain, controls our body's core temperature. The hypothalamus measures our body's temperature and compares it to the average temperature, which is around 37 degrees Celsius.

The hypothalamus ensures that the body produces and maintains heat if our body temperature falls too low.

Progesterone tends to encourage heat conservation and higher body temperatures, whereas estradiol tends to increase heat dissipation.

Therefore, a thermostat seen in homes is the most basic type of temperature controller.

Q6.2. There are many diseases that do not infect a person more than once, such as chicken pox
and measles. What is responsible for this lifetime immunity?

The innate immune response, because barriers to entering the body improve with age.

The innate immune response, because adults have more white blood cells than children.

The acquired immune response, because antibodies are developed from previous infections.

The acquired immune response, because it responds rapidly to broad classes of pathogens.

Answers

The responsible for this lifetime immunity is the acquired immune response because antibodies are developed from previous infections. The generation of antibodies is a response to these infections.

The acquired immune system eliminates pathogenic organisms and any toxic molecules they produce.

The acquired immune system has two mechanisms of action: humoral immunity and cellular immunity.

Humoral immunity, also known as antibody-mediated immunity, involves the activation of specific blood cells (B cells) and subsequent secretion of antibodies when in contact with a pathogen.

Thus, the acquired immune system develops specific antibodies as a response to infections (e.g., chickenpox and measles).

Explain how scientists use geologic time to determine the age of landforms.

Answers

Answer:

scientists have developed four different methods of determining the age of the earth. By using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined.

Based on the research done by scientists, the Geologic Column, a graph that illustrates earth age, was developed. The Column, with its names for the epochs and eras of time, illustrates what scientists think was taking place in earth history. The three primary methods are:

Radiation Measurement

Stratigraphic Superposition

The Fossil Record

From these methods of dating, scientists have determined that the earth as we know it seems to be about 4.6 billion years old. It is theorized that the earth got its start as a result of what is called the "Big Bang nearly 6 billion years ago. The Big Bang theory holds that all the planets, stars, solar systems, galaxies, etc., are the result of a huge explosion that sent material speeding through space. As time passed, the gravitational force of larger chucks of material attracted the smaller chunks and formed the galaxies and solar systems we see today.
